Stroke property for feFlood filter

Hi Cameron,

height="400">
>     <rect id="theTextBackground"
fill="yellow" width="0"
height="0"/>
>     <text id="theText"
x="100" y="100">This is some
text.</text>
>     <script>
>       var r =
document.getElementById("theTextBackground");
>       var t =
document.getElementById("theText");
>       var bbox = t.getBBox();
>       r.setAttributeNS(null, "x", bbox.x);

>       r.setAttributeNS(null, "width",
bbox.width);

bbox.height);

getBBox and getComputedTextLength is returning the required
values 
after 'Text' Element has added in RootElement. But is it
possible to create 
the rectangle while creating the 'Text' Element?

Element text = doc.createElementNS(svgNS,
"text");
Text value =
doc.createTextNode("100.100.10.10");
text.appendChild(value);
text.setAttributeNS(null, "text-decoration",
"none");
text.setAttributeNS(null, "x",
"150");
text.setAttributeNS(null, "y",
"150");
text.setAttributeNS(null, "font-family",
"Arial");
text.setAttributeNS(null, "font-size",
"12");
text.setAttributeNS(null, "width",
"???") //i need to set width here.

Thanks,
Selva

Yes.

  Element text = doc.createElementNS(svgNS,
"text");
  Text value =
doc.createTextNode("100.100.10.10");
  text.appendChild(value);
  text.setAttributeNS(null, "text-decoration",
"none");
  text.setAttributeNS(null, "x",
"150");
  text.setAttributeNS(null, "y",
"150");
  text.setAttributeNS(null, "font-family",
"Arial");
  text.setAttributeNS(null, "font-size",
"12");
  rootElement.appendChild(text);
  var bbox = text.getBBox();
  Element rect = doc.createElementNS(svgNS,
"rect");
  rect.setAttributeNS(null, "x", bbox.x);
  rect.setAttributeNS(null, "y", bbox.y);
  rect.setAttributeNS(null, "width",
bbox.width);
  rect.setAttributeNS(null, "height",
bbox.height);
  rect.setAttributeNS(null, "fill",
"yellow");
  rootElement.insertBefore(rect, text);
